Former Wimbledon finalist Sabine Lisicki is seeking a new coach after announcing a split with Christopher Kas.
Lisicki reached a high of 12th in the WTA rankings four years ago and finished as the runner-up to Marion Bartoli at Wimbledon the following year.
However, the grass-court specialist has since slumped to 50th in the world, managing just one quarter-final appearance thus far in 2016.
In a post shared on her official Facebook and Twitter accounts, Lisicki wrote: "Christopher Kas and I will no longer work together. It's been a very intense couple of years, I thank him for all the work and support through this time and wish him all the best for the future!
"A new chapter starts right now. This means I will soon be represented by a new management and I will have a new coach by my side."
